R = CRect:new()
R = CRect:new( CRectOld )
R = CRect:new( xmin, xmax, ymin, ymax )
R = CRect:new( CImage )
R = CRect:new( CPoint )
R = CRect:new( array )
where
The first form,
with no arguments, creates a default CRect object
R with properties initialized to
0,0,0,0.
CRectOld is an existing CRect object. This form
creates a new CRect object initialized to the properties of
CRectOld.
xmin, xmax, ymin, ymax. are numbers. This form
creates a new CRect object initialized to these 4
values.
CImage is a CImage object. this form creates a
new CRect object initialized to the column and row
dimensions of the CImage. The CRect properties will extend
from 1 to CImage:Cols(), and 1 to CImage:Rows().
CPoint is a CPoint object. A
new CRect object is created with its properties set to xmin=1, xmax=CPoint.x, ymin=1, and ymax=CPoint.y.
array is a lua table containing at least
indicides 1 through 4. Thie form creates a new CRect object with
its properties set to the first 4 values in the array. The
properties are set to xmin=array[1],
xmax=array[2], ymin=array[3],
ymax=array[4].
R is the new CRect object. On failure, 0,0,0,0 is returned.
